HAIRPIN Filed April 19, 1946 INVENTOR ATTORNEY Patented July 19, 1949 HAIRPIN Edward Bergen, Bronxville, N. Y., assignor to Hold-Rite (30., New York, N. Y., a firm Application April 19, 1946, Serial No. 663,263

3 Claims. (Cl. 132-50) My invention relates to hairpins and refers particularly to hairpins of such construction as to prevent their accidental removal from hair enclosed therein.

Among the necessary properties which are desirable in satisfactory hairpins are that they should be inexpensive in production, simple in construction, easy to insert in a plurality of hair strands, so constructed that they will be automatically restrained from dropping from the hair or from being accidentally removed therefrom, and that they will not unduly pull the hair during their insertion into and removal from the plurality of hair strands.

A consideration of the hairpins of my invention will indicate that they possess all of the above-mentioned, and other valuable properties.

In the accompanying drawings illustrating modified forms of the hairpins of my invention, similar parts are indicated by similar numerals.

Figure 1 is a side view of one form of a hairpin of my invention.

1 Figure 2 is a bottom view of the device of Figure Figure 3 is a section through the line 3-3 of Figure 1.

Figure 4 is a section through the line 44 of Figure 1.

Figure 5 is a side view of a modified form of a hairpin of my invention.

Figure 6 is a bottom view of the device of Figure 5.

Figure 7 is a section through the line I-| of Figure 5.

The particular form of a device of my invention shown in Figures 1 to 4 comprises a unitary construction of resilient material with the lower concave leg l having the return bent portion l i, which is expanded into the broader portion l2, and then extended into the upper leg which is formed by the two spaced flat undulated extensions l3, l3 of the portion l2, the two undulated extensions l3, l3 being connected by an arcuate bar M at their extremities, the lower leg extremity l being preferably longer than the upper leg terminal l4.

While the lower leg portions l0 and H are shown as being concave, they may be of fiat formation, the concave formation being preferred as it gives increased upward resilient pressure of the leg I0 into the space between the upper leg portion l3, l3 when in normal position as shown in full lines in Figures 1 and 4.

In operating the device, the lower leg [0 is lowered into the position shown in the broken line,

hair is placed between the two legs of the device and the lower leg I0 is allowed to return to its normal position.

It will be noted that if the device is moved into a plurality 0f hair strands, the extended portion l5 of' the lower leg will allow the hair to be moved inwardly between the two legs, and the resiliency of the leg in will force the hair upwardly into the lower valleys of the upper leg portion l3, l3, forming a plurality of undulations of the hair and thus preventing the accidental removal of the device.

The particular form of my device shown in Figures 5 to 7 is similar to that shown in Figures 1 to 4, except that it is formed from a single piece of wire.

This forming of my device comprises a piece of wire 20 turned upon itself at 2! to form two spaced parallel undulated members 22, 22 forming the upper leg. The two free end portions of the wire 20 are then turned upon themselves at 23 into parallel position to the upper leg and are twisted around each other forming the lower leg 24.

The operation of this device is similar as that described for the device shown in Figures 1 to 4.

It will thus be seen that my invention presents a simple and inexpensive hairpin, adapted particularly for easy insertion between a plurality of hair strands, and of such construction as to prevent it from accidental removal therefrom.

I do not limit myself to the particular size, shape, number, arrangement or materials mentioned and described, as these may be varied without going beyond the scope of my invention.

What I claim is:

1. A hairpin comprising a leg formed from a strip of concave resilient material, one end portion of which is widened and turned upon itself forming a corrugated leg having a centrally longitudinally positioned opening therein, the said first mentioned leg having an inner transverse concave surface and being narrow enough to allow its being resiliently positioned within said opening of the corrugated leg when the hairpin is in normal position.

2. A hairpin comprising a first leg having an inner transverse concave surface; a second leg having a pair of parallel longitudinal elements; a bar interconnecting said elements at one end; and means having an inner, transverse concave surface connecting the other ends of said elements of the second leg to the first leg; said first leg being bent in the form of a bow and biased inwardly into mesh engagement with the elements of said second leg.

, 3. A hairpin in accordance with claim 2, in

which the elements of the second leg are corrufile of this patent:
